In human terms we would like to think that this photo shows a love bond between mother and cub although this may be true in this case the cub wanted to nurse. Grizzly cubs generally stay with their mother for two years; some will stay for three or four if she does not become pregnant in the fall of their second year. Grizzly bear are extremely good mothers, and, consistent with the high level of “investment” they make in their cubs to ensure their survival, they are very protective of them. Because of this, encountering a grizzly bear with young can be very dangerous. During the first two years of their lives, the sow will teach her cubs everything they need to know to survive on their own. She will school them in finding and exploiting different food sources, and the cubs spend significant time observing her actions and learning them for themselves.
